Application 1ed1M`ay23`, 1911. Serial No. 629,014.

To all whom it mag/concern:

Be it known that I, BENJAMIN F, CAR- PENTER, a citizen of the United States,lresiding at 65 Orchard street, Summit, county of Union, and State of New Jersey, have invented certain new and useful Improve-- The invention embraces` primarily a=hood to inclose the top/of the stove and having a segmental roll-top which can be turned to open the upper part of the hood.

The invention also embraces means for counterbalancing the hood and moving it upward from the stove-top when access to the entire top is desired. The invention thus combines the advantages ofr the rolling hoods and. the balanced hoods heretofore used.

To guide the hood when lifting it fromA the stove-top, the usual grooved posts are extended upward from the edges of the stove-top and the opposite sides of the hood fitted movably thereto, and a-cur-tain connects the top of the hood with a spring shade-roller journaled between the tops of the posts, to confine the heat and` vapors within the hood.- When these improvements are appliedto a portable stove or range the posts are connected with the front corners of a hot closet which extends backwardly from the posts over the rearhalffof the stove-top as shown in the drawing herewith.

In the following description it will be understood that the term hood is used to include all the parts which are movable between the posts, excepting the curtain which connects the top of the hood with the curtain-roller. These movable parts embrace a rectangular base' adapted to fit closely upon the top ofI the stove or range, a yoke having side-bars projected upwardv from the ends of the base andI connected by a top yoke-bar having an' attachment for a curtain, and a roll-top journaled between the side-bars and adapted to swing to and from the front of the base' to cover or expose` the topof the same aty pleasure. i

` The invention includesvarious details ofi construction whichwill be understood by PatentetlSept. 10,1912.

Also the pulleyfu, cleat' u andthe fold o are omitted in the upper part` of this figure. Fig.. G` is an elevation of the shade-roller adjusted; Fig. 7 is a plan of the stove-top 4 with the ends and back ofthe hot closet and the hood-base'.` Fig. 7 is on a small scalef and the4 details of construction are omitted as Fig. 5 exhibits them fully. Fig.

of a range.` l

A st oveA is shown in Fig; 1, the posts B for guldingthe hood'restingupon the stovetop C. A hot closet D is extended baclr wardly fronrtlie rear edges of the posts and sheathing N extends upwardly from the top of the closet between the rear edges of the posts'to a cornice at their upper end. The base of the hood is formed with end baseplates af and front b having a sliding door c fitted therein.l A yokeis provided to suspend the hood from the shade-roller F by means of a flexible curtain G. The yoke is preferably formed with end-bars'H-4 of trough-shape affixed tol the base-plates a by flanges secured byrivet-s H, and extend ing above the same to a top-bar I having a flange I at its rear edge for the attachment' projected inwardly from the end-bars H adjacent to the base-.plates a, and the rolltop is formed with segmental front J and triangular end-plates K which are journaled upon the said pivots g by journal plates K. The front J is formed with a sliding door J and glass panels L are shown in the door and in the adjacent portion of the roll-top. The end-plates K of the roll-top are riveted to the journal-plates K, and a spirally coiled wire h has its inner end engaged with a groove in the pivot g and its outer end bent radially to engage any one of a series V'of lugs z' upon the plates K carried by the pivots g. Such wire spring is adjusted to substantially balance the weight of the movable roll-top.

It will be observed in Fig. 3 that the rolltop extends from the upper edge of the base to the front corner of the top yoke-bar I which projects forward from the line o f the posts so that the curved segment is matel rially less than a quadrant of a'circle, and when turned baclrwardly beneath the top yoke-bar I, as shown in dotted lines J2 in Fig. 2, it therefore projects but a short distance into the hot closet D. The hot closet is shown with a shelf D and a glass window j in its roof to light the closet and stove-top. A smoke-pipe 7c extends upwardly from the stove-top C through the roof of the hot closet and through the shelf Y D', and is provided with an elbow .70 to oonneet it with the chimney. A damper M is shown in the smoke-pipe c. A sheathing N extends upwardly from the top of the hotcloset to the cornice N connecting the ends of the posts, and a Ventilating pipe O is extended from the sheathing to the chimney O, and provided with a damper. The space between the curtain G and the sheathing N is nearly equal to the width of the posts and affords ample room for the gases and vapors in the hood and hot closet to pass upwardly to the Ventilating-pipe O.

It is evident that the entire draft of the chimney may be concentrated upon the ventilating-pipe by closing the stove-pipe damper M, or upon the stove-pipe by closing the Ventilating damper P, or in any intermediate degree by suitably adjusting the two dampers. The construction of the posts is shown in Fig. 5, with an exterior shell formedof a sheet-metal strip m having inwardly turned flanges m at its opposite edges, giving it a trough-shape combined with an interior piece of sheet-metal having two attached portions a and n bent to a right angle to form a pocket for the counterbalance weight- Q, and the portion a bent to form a trough y and its edge-flange n2 extended parallel with the flange m. Pulleys u are provided in the upper part of the posts to sustain the cord for the counterbalance-weight, one such pulley being shown in the lower part of Fig. 5, but omitted from the upper part to show the weight more clearly. The trough g serves as a guidegroove for the guide-rolls u pon the hood, and the space between the flanges n2 and m serves as a guide for the ends of the curtain-bar al. The adjacent outer edges of the flanges n2 and m are rolled inwardly to stiften them at opposite sides of the trough which guides the curtain-bar. A strap s encircles the outer sides of the posts at the bottom and is secured thereto by rivets s', and has its inner end twisted to form a foot t to rest upon the stove-top to which it can be secured by bolts inserted through holes t if desired. There the posts are set directly upon the top of the stove, the sheathing is extended upwardly from the top of the closet, as shown in Fig. 2, and the posts are provided, as shown in Fig. 7, with cleats having a vertical double fold u adapted to engage double folds o upon the forward corners of the hot closet, which serve to keep the hotcloset ing suitable connection with the posts and the hood. The cleats are fastened to the plates m above the straps s, and in order to show clearly the connection between the foot t and the strap s, the cleat is omitted in the upper end of Fig. 5, but shown above the foot at the lower end of this figure. downwardly flanged at the edges and lits detachably into channels w formed upon the upper edges of the closet, as shown in Fig. 2, so that the body of the closet and its cover are readily detachable from one an other and from the posts, to facilitate transportation.

From the above description it will be seen that the hood has a rectangular base-portion which, when the hood is lowered, rests upon the to-p of the stove and wholly protects the cook from the spattering of fat or water from any vessels upon the stove-top. The door upon the hood furnishes access to the stove-top without raising the hood. If the roll-top be closed at such time all the emanations are confined within the hood and are led upwardly behind the curtain G to the Ventilating-pipe O. The roll-top is balanced upon the hood so that it can be set open to any given amount or can be wholly opened to examine articles upon the stovetop to stir them or to shift them about or remove them entirely. Vhen the roll-top is closed, its door J may be opened for ac cess to any particular article, the window L furnishing additional light at such times to the interior of the hood. When the rolltop is opened, access to the hot-closet is afforded without raising the remainder of the hood, as the shelf in the closet is readily accessible beneath the top-bar I of the yoke. When desired, the entire hood may be raised, as shown in Fig. 1, thus affording access at once to the entire stove-top.

The device furnishes all the advantages of a balanced canopy, that can be raised or` lowered over the stove-top, and also the advantage of a roll-top which, without the effort of raising a canopy, can be turned upwithin the hood, second, in protecting the person and clothingof the cook from heat, flame, and spattering during the cooking operations, third, in affording access to a portion of the stove only for such operations, as broiling, toasting, frying, han-` dllng laundry irons, &c., while confining thel heat largely to the top of the stove, fourth, in controlling the temperature within the apparatus for cooking and other purposes, and thus regulating the temperature of the kitchen by preventing the radiation of heat and the iiow of hot air from the stove, fifth, in affording access to the hot-closet through the roll-top while protecting the person from the hot stove-top by the base of the hood, and finally, in affording means for lighting the hot-closet and the interior of the hood by panels of glass in the various parts.

The parts operate most satisfactorily when the entire hood is rather underbalanced by the weights Q, and then balanced accurately by adjusting the tension of the curtainroller F to exactly balance the hood in any position so that when raised or lowered it will retain such position. The adjustment of the roller is in practice effected by the means shown in Fig. 6, consisting of a crank-arm fitted to the roller-spindle m of the shaderoller and having a knob y upon the end by which it may be readily turned in a manner well known to tighten the spring of the shade-roller; being locked when the desired tension is attained by engagement with .any

one of a series of notched studs e xed upon the end of the roller-housing. In like manner, the roll-top J is adjusted by setting the coiled wire spring 7L in connection with a suitable locking lug z', as shown in Fig. 3. The spiral balanced spring in this construction is, unlike those heretofore used, made of dish-shape; so that the outer end of the spring lies in a diiferent plane from the inner, as is distinctly shown in the upper part of Fig. 4, so that a washer h may beadjusted upon the pivot g to compress the coils of the spring more or less and crowd the journal-plate K of the roll-top against the shoulder upon the pivot, shown at g in the lower part of Fig. 4. Such adjustment of the washer is effected by the use of a slot g2 in the pivot (shown in the lower part of Fig. 4), and a step-key h2 shown in Fig. 4a, which may be fitted into the slot outside of the washer and inserted suffisprings 7L. 1"

cientlylto compress the spring in the desired degree.j Y The friction thus produced between the journal-plates' K and the shoulder g serves to prevent the segmental front J from moving accidentally from any position in which it is placed, as yit would be liable to do vif held in exact equilibrium Vby the `Having thus invention what is claimed herein is:
